The increased availability of noninvasive breath tests, each with limitations, has led to widespread testing for small intestinal bacterial overgrowth (SIBO) in patients with non-specific gastrointestinal complaints. The lactulose breath test (LBT) is based upon an incorrect premise and therefore incorrect interpretations which has resulted in the over-diagnosis of SIBO and the excessive use of antibiotics in clinical practice. Despite limitations, the glucose breath test (GBT) should be… 
Every Breath Test You Take: Practical Advice on Breath Testing Used to Detect Small Intestinal Bacterial Overgrowth
The review explains that additional false positive results may arise from the discharge of endogenous mucopolysaccharides present in secreted mucus or transfer of residual ileal carbohydrates to the colon with subsequent metabolism and release of the gases by the normal colonic microbiome (gastroileal reflex).
Prevalence of small intestinal bacterial overgrowth syndrome among patients with inflammatory bowel disease and its impact on nutritional status and clinical manifestations
A high prevalence of small intestinal bacterial overgrowth (SIBO) syndrome is found in patients with IBD depending on the nosological forms and its effect on clinical and laboratory indicators of nutritional status and clinical manifestations is investigated.
Bile Acid Malabsorption in Patients with Neuroendocrine Tumors
A majority of patients with NET and diarrhea had BAM, even with < 25 cm or no IR, and there were significant correlations between total FBA and 48-h fecal weight.

Advances in the identification of specific dysfunctions as causes of individual symptoms in the "IBS spectrum" leads to the potential to enhance the diagnosis and management of symptoms for the majority of patients for whom first-line therapies of IBS andmanagement of comorbid psychological disorders are insufficient.
Intestinal bacterial overgrowth in the early stage of severe acute pancreatitis is associated with acute respiratory distress syndrome
Intestinal bacterial overgrowth in the early stage of SAP is correlated with ARDS, and early clinical intervention and maintenance of intestinal barrier function would be highly beneficial in controlling the development of severe acute pancreatitis (SAP).
Chinese herbal medicine for the treatment of small intestinal bacterial overgrowth (SIBO)
A systematic review focusing on efficacy of CHM in the treatment of SIBO with PCOS aims to comprehensively explore it and will provide high-quality evidence to help patients, clinicians as well as health policymakers select better treatment strategy of PCOS.

Diagnostic standards for overgrowth of methanogens are ambiguous, as the understanding of this phenomenon is still in its infancy, and the semi-quantitative hydrogen breath test has been proposed as an alternative to intestinal bacterial culture for SIBO diagnosis.

Use and abuse of hydrogen breath tests
Hydrogen breath tests are widely used to explore the pathophysiology of functional gastrointestinal disorders and there is extensive use of these tests in clinical practice with difficulties regarding interpretation of the tests and sometimes erroneous conclusions.

BT is a useful, inexpensive, simple and safe diagnostic test in the evaluation of common gastroenterology problems and should help to standardize the indications, preparation, performance and interpretation of BT in clinical practice and research.

Small intestinal bacterial overgrowth: duodenal aspiration vs glucose breath test
The aim was to examine the diagnostic yield of duodenal aspiration/culture and glucose breath test (GBT), and effects of gender, race and demographics on prevalence of SIBO.

OBJECTIVES To i) document the sensitivity and specificity of a combined scintigraphic/lactulose breath hydrogen test for small intestinal bacterial overgrowth and ii) investigate the validity of
Small intestinal bacterial overgrowth in patients with irritable bowel syndrome
The data do not support an important role for SIBO according to commonly used clinical definitions, in irritable bowel syndrome, however, mildly increased counts of small-bowel bacteria seem to be more common in IBS, and needs further investigation.
Combined oro-caecal scintigraphy and lactulose hydrogen breath testing demonstrate that breath testing detects oro-caecal transit, not small intestinal bacterial overgrowth in patients with IBS
It is demonstrated that an abnormal rise in H2 measured in the LHBT can be explained by variations in oro-caecal transit time in patients with IBS and therefore do not support the diagnosis of SIBO.
